At age 20, she reverse-engineered the Apple GPU. At age 40, I got the LED to blink on my Arduino.
I mean I have decades of doing all sorts of IT work and this is way beyond my level. Absolutely amazing.
I have such immense respect for people who know how the bits are physically flowing through a machine. I took classes about it but I can't imagine doing that daily, it's so tedious.
yeah I remember not being able to get my voltron lion to run in basic when I was in junior high.
And imagine doing it without expecting a cent!
It’s the challenge of it though.
thaaaaat’s the shit, when it finally cracks and you laser focus on implementing your solution. better than drugs.
The high of cracking an intractable problem (pre-AI) was just unreal. I’d struggle to sleep, awaiting the morning so I could get back at it.
Nothing groundbreaking but writing my own Huffman compressor in C and seeing the whole thing work knowing where nearly all the real physical bits were going, was seriously satisfying. Recommended exercise ☺️
‘Just for the lulz’.
Good on a resume.
That's for sure
You mean you can't just get Apple's driver to work on Linux by turning it off and on again enough times?
or even by recompiling the kernel when apples driver is not part of it.
If you can’t get the Arduino lights to blink at this point I can only applaud your persistence
Wins no matter how small are wins!
Don’t compare yourself to others, just enjoy the learning process & satisfaction it hopefully brings you for every single win, no matter the size!
Arduino is a fantastic platform for learning, I still remember a lot of my ‘firsts’ with it, I had no idea what I was doing, we all start somewhere. Have fun!
While I agree partially, want to mention that having someone to compare to is not as bad as it sounds. Its only bad if you think its unreachable and you give up doing anything. Sometimes you need a hero to look up and fight and dream about it, for the motivation. I think looking up to people like Alyssa's work is inspirational. In a similar way how I look up to those magicians who create emulators... but that is a different topic for another day.
What a wholesome comment
It all adds up ⬆️
I used a toothpick to get some apple shell unstuck from my gum.
... by yourself !?
Impossible, that's what we have fish for.
I'm 30 and I wiped my own ass. So I'm feeling pretty accomplished.
You must be male
Any other female crusters? #LetItCrustQueens
The bar is subterranean
I sure do love when self-deprecation is used as fuel in gender wars.
